A disaster awaits Alonso at Chelsea.

On the night of May 24th, Sunderland celebrated their Europa League qualification as a historic achievement, while Chelsea left the Stadium of Light looking like a team lacking direction.

The 1-2 defeat in the final round of the Premier League not only knocked the London team out of all European competitions next season, but it also exposed the complete breakdown within a team once considered a contender to return to the Champions League.

Chelsea played poorly against Sunderland in the final round of the Premier League.

The worrying thing for Chelsea isn't the scoreline, but their attitude. The Daily Mail describes them as a team that "lacks seriousness and is full of a sense of entitlement."

Apart from Levi Colwill, who played with fighting spirit, the rest of the defense seemed to have given up before the game even started.

Chelsea conceded a goal from a simple long ball situation. Malo Gusto scored an own goal in a baffling way.

Wesley Fofana received a red card while his team was struggling, marking Chelsea's 10th red card of the season. This number clearly reflects a lack of control in the team's overall performance.

What's even more bitter for Chelsea fans is that Sunderland won thanks to spirit and desire, something the Blues have almost completely lost.

Four years ago, Sunderland were playing in League One, and now they're preparing to compete in Europe. Meanwhile, Chelsea, with a squad that cost billions of pounds, ended the season with disappointment and apologies.

Interim manager Calum McFarlane admitted that Chelsea should have been in the Champions League with the quality of their current squad.

Alonso has a host of problems to solve at Chelsea.

But Chelsea's problems this season have never been just about performance. It's about inconsistency, a lack of character, and a dressing room that no longer feels like a team fighting for a common goal.

Xabi Alonso will arrive at Stamford Bridge this summer with the reputation of a modern manager with a strong tactical personality. But what awaits him is not a team ready to compete for titles, but a squad in need of a major overhaul.

The absence of European competition means Chelsea doesn't need to maintain such a large squad. A mass exodus is entirely possible.

Wesley Fofana is likely not the only name on the transfer list. Enzo Fernandez's future is also uncertain amid rumors of a reunion with Enzo Maresca at Manchester City.

Even Cole Palmer, who scored the most beautiful goal of the match, can no longer maintain the explosive form that once captivated the entire Premier League. Chelsea currently has no shortage of talent, but they lack the cohesion and discipline of a top team. That is the biggest challenge facing Xabi Alonso.
